Their father, Caliph Harun al-Rashid, had named al-Amin as the first successor, but had also named al-Ma'mun as the second, with Khurasan granted to him as an appanage. Later a third son, al-Qasim ibn Harun al-Rashid, al-Qasim, had been designated as third successor. After Harun died in 809, al-Amin succeeded him in Baghdad.
